AF-S DX Nikkor 17-55mm f/2.8G IF-ED

The Nikon AF-S DX Zoom-NIKKOR 17-55mm f/2.8G IF-ED is a standard zoom lens designed for Nikon F-mount DX-format cameras, providing a 25.5-82.5mm equivalent focal range. The lens features a constant f/2.8 maximum aperture throughout its zoom range, which enables consistent light transmission and precise control over depth of field for selective focus work. The optical design incorporates three aspherical elements and three extra-low dispersion elements to minimize spherical and chromatic aberrations, while a Super Integrated Coating reduces internal reflections and improves contrast and color accuracy.

The lens employs a Silent Wave Motor autofocus system that delivers fast and accurate focusing with full-time manual focus override capability. A rounded nine-blade diaphragm produces pleasing out-of-focus quality that supports shallow depth of field techniques. The internal focusing design maintains the lens length during focusing, which contributes to faster autofocus performance and a minimum focus distance of 1.18 feet.
